World’s smallest quartz frequency devices drive IoT and wearable design
Three offerings from AEL Crystals reduce the size of the core technology for wearable and IOT devices, says the company.
They are the 1610 watch crystal; the 1210 crystal; and the 1612 oscillator.
The 1610 watch crystal is the world’s smallest 32.768kHz watch crystal, claims the company. It measures 1.6 x 1.0 x 0.5mm (maximum). The wide operating temperature ranges from -40 to +105°C. Initial stabilities can be specified between ±10 and ±50ppm, for wireless modules, in-car devices, Bluetooth devices and mobile phones, as well as wearable devices, such as smart watches, fitness trackers, medical and activity monitoring devices.
ESR (Equivalent Series Resistance) is 60k? (maximum), making the watch crystal suitable for low ESR applications such as Bluetooth Low Energy chipsets. Furthermore, AEC-Q200 compliant versions are available, for use in the automotive industry.
The 1210 crystal is claimed to be the world’s smallest crystal and measures just 1.2 x 1.0 x 0.33mm (maximum). It can be supplied between 36.0 and 80.0MHz. Operating temperature can be specified from -40 to +125°C, with temperature stability from ±10 to ±50ppm and initial stability as low as ±7ppm. AEC-Q200 compliant versions are also available.
According to the company, the world’s smallest oscillator is the 1612. It measures just 1.6 x 1.2 x 0.7mm (maximum) and operates across a temperature range from -40 to +85°C. Temperature stability is ±10 to ±50ppm, and initial stability of ±7 to ±50ppm. Operating frequency range is 1.0 to 80.0MHz and the oscillators operates from a 1.8, 2.5 or 3.3V supply.
